论女性、性别与休闲问题

在过去的近三十年里,女性、性别与休闲研究经历了不同的发展阶段。学术界已经开始从女性主义视角来研究女性、性别和休闲,其目的就是要了解这些现象,从而推进男性和女性这两种不同的休闲生活的社会变化。在探讨女性及休闲的不同研究阶段的同时,总结英语国家的研究收获,并就如何从不同文化视角来探讨上述观点提出几点建议。     

Mental health issues and the foster care system: an examination of the impact of the Adoption and Safe Families Act

Although marriage and family therapists are being called on to help at-risk families, some say that clinicians have insufficient knowledge about the impact of policies on families involved in the foster care system. The purpose of this qualitative investigation was to identify how the Adoption and Safe Families Act informs decision making, to recognize trends in decisions regarding termination of parental rights of parents with mental health issues, and to explore treatment issues of families involved in the foster care system. Results indicate that court cases decided after the implementation of the Adoption and Safe Families Act are likely to result in termination of parental rights. Implications for clinicians and researchers are discussed.     

LMX differentiation: A multilevel review and examination of its antecedents and outcomes

We examine antecedents and outcomes of leader–member exchange (LMX) differentiation, or the variability in LMX patterns within work groups. Individual-level characteristics and behaviors of leaders and followers, group context, and organizational context variables are presented as antecedents. We review and offer theoretical extensions to research examining the outcomes of LMX differentiation at the individual, group, and organizational levels. Our aim is to contribute to a meso-model of leadership and stimulate research that attends to the core element of the LMX model–LMX differentiation.     

Modelling Converging Hazards in Survival Analysis

The Cox proportional hazards model has become the standard model for survival analysis. It is often seen as the null model in that "... explicit excuses are now needed to use different models" (Keiding, Proceedings of the XIXth International Biometric Conference, Cape Town, 1998). However, converging hazards also occur frequently in survival analysis. The Burr model, which may be derived as the marginal from a gamma frailty model, is one commonly used tool to model converging hazards. We outline this approach and introduce a mixed model which extends the Burr model and allows for both proportional and converging hazards. Although a semi-parametric model in its own right, we demonstrate how the mixed model can be derived via a gamma frailty interpretation, suggesting an E-M fitting procedure. We illustrate the modelling techniques using data on survival of hospice patients.     

Spiritual development and camp experiences

Camps have long addressed multiple components of young people's development, including spiritual development. In particular, transcendental communion with nature and the outdoors may provide one pathway for young people's spiritual development.     

Maternal neural reactivity during pregnancy predicts infant temperament

Maternal biological systems impact infant temperament as early as the prenatal period, though the mechanisms of this association are unknown. Using a prospective, longitudinal design, we found that maternal (N = 89) amplitudes of the late positive potential (LPP) in response to negative stimuli during the second, but not the third, trimester of pregnancy predicted observed and physiological indices of temperamental reactivity in infants at age 4 months. Maternal LPP was positively associated with observed infant fear and negatively associated with frontal EEG asymmetry and cortisol reactivity in infants at age 4 months. Results identify a putative mechanism, early in pregnancy, for the intergenerational transmission of emotional reactivity from mother to infant.     

World society and the natural environment

We review the world society approach to explaining macrohistorical change generally and as it relates to the natural environment specifically. Our review includes work describing the rise of the environmental world society as well as empirical evidence of the consequences of national ties to world society for policy adoption, practices, and individual attitudes at the national level. Additionally, we suggest the application of world society theory to state and substate structures. Throughout the review, we situate the world society literature in relationship to work in the fields of cross‐national comparative and environmental sociology from a variety of other perspectives. We take a forward‐looking approach to our review of theoretical and empirical work in the field and consider the implications for normative change and resistance to prevailing world cultural norms. We conclude with a discussion of the resurgence of nationalism especially as it relates to antienvironmentalism.     

An Introduction to Nonparametric Regression for Labor Economists

In this article we overview nonparametric (spline and kernel) regression methods and illustrate how they may be used in labor economics applications. We focus our attention on issues commonly found in the labor literature such as how to account for endogeneity via instrumental variables in a nonparametric setting. We showcase these methods via data from the Current Population Survey.     

The governance of primary mental health planning by Primary Health Networks

The establishment of Primary Health Networks (PHNs) was accompanied by assignment of responsibility for funding for primary mental healthcare. To ensure this funding is spent in line with government priorities, the Federal government developed a planning document with established priorities and guidance documents for how the planning document should be completed. This paper examines how these documents shape service delivery through enabling some activities and excluding others and identifies the assumptions that underpin these documents. Data were drawn from discourse and content analysis of completed planning documents from the PHNs and of the guidance documents and from reflection upon mental health planning from 55 interviews with key personnel from six PHNs. Service delivery is shaped by outcome measures that promote service access, cost‐effectiveness and clinical effectiveness, contributing to service options that favour self‐management for mild mental illness and clinical (but not social) services for people with severe mental illness. There is also limited scope for mental health promotion with prevention activities focused upon populations identified by the government as being at‐risk. This occurs to the detriment of other at‐risk populations.     

Exploring changes in treatment effects across design stages in adaptive trials

The recently published Committee for Medicinal Products for Human Use reflection paper on flexible designs highlights a controversial issue regarding the interpretation of adaptive trials. The guideline suggests that a test for heterogeneity should be preplanned and if treatment effect estimates differ significantly between design stages then data collected before and after the interim analysis might not be combined in a formal analysis. In this paper we investigate error rates for such a procedure in the presence of calendar-time effects. Furthermore, we present an alternative testing strategy based on change point methods. In a simulation study we demonstrate that our procedure performs well in comparison to that suggested by the guideline.
